Answer:
Step-by-step explanation:
Given that there are three variables satisfying the equation
Here each x is given to be a positive integer
i.e. solution set for each of the variable can be any integer from 1 to 20 at most.(because if two other integers are 1 each third has to be 20)
Hence solution set can be of the form
If x1 =1, there are 20 solution sets
If x1 =2,there are 19
...
If x1 =20 there is 1 set
Hence total solutions can be
If you multiply $1500 by 0.04 which is 4% you get $60 from the interest and if you multiple $1560X0.04=$62.40 and if you repeat the posses 1 more time you earn $64.90 more from interest so in total it was three blocks of 4% interest was earned.<span />
Answer:
D). 2.4 
Step-by-step explanation:
Mary is driving toward north so the angle is 90° and Danny is driving toward the east so angle is 0°
Momentum Dary= 
Momentum Danny= 
So the total momentum is the magnitude:
Mag= 
mag= 
≅
14 is 81% because I just put it into a calculator
Answer:
( 19/3, -1)
Step-by-step explanation:
3x + 4y = 15
3x + 4(-1) = 15
3x -4 = 15
3x= 19
x= 19/3
